Alarm clock dropped inside wall still going off daily after 13 years

Thirteen years ago, Pittsburgh's Jerry Lynn carefully lowered an alarm clock on a string, lowering it into a wall from the floor above, part of a cunning plan to identify where to drill a hole by waiting for the alarm to go off. Unfortunately, the string snapped, and the clock's been going off daily ever since.

As I was laying it down, all of a sudden I heard it go thunk! as it came loose, he said. I thought, well, thats not a real problem. You know its still going to go off. And it did.

He couldnt pull it back up, but figured, Maybe, three-four months itll run out of battery. That was in September of 2004. It is still going off every day. And during daylight savings time it goes off at ten minutes til eight. And during standard time it goes off at ten minutes to seven at night.
